I tried to find something in that commit that would be different
in compat mode, but don't see anything at all -- this appears
to be just a simple refactoring of the code, unlike the commits
that immediately follow it and that do change the mount
interface.

Unfortunately this makes it impossible to just revert the commit
on top of linux-next. Can you double-check your bisection by
testing 546694b8f658 and the commit before it again?

What are the exact mount options you pass to autofs in your fstab?
